## Conversion formula

The conversion factor from decimeters to millimeters is 100, which means that 1 decimeter is equal to 100 millimeters:

1 dm = 100 mm

To convert 492 decimeters into millimeters we have to multiply 492 by the conversion factor in order to get the length amount from decimeters to millimeters. We can also form a simple proportion to calculate the result:

1 dm → 100 mm

492 dm → L(mm)

Solve the above proportion to obtain the length L in millimeters:

L(mm) = 492 dm × 100 mm

L(mm) = 49200 mm

The final result is:

492 dm → 49200 mm

We conclude that 492 decimeters is equivalent to 49200 millimeters:
